    1. Solve by substitution:
    x + y = 6
    2x - 4y = 0

    2. Does the shaded region of the graph of the system of equations x < 3, x
    + 7< 4 include the point (2, 3)? How do you know?

    3. Explain what it means for a system of equations to be inconsistent and
    how you can tell whether a system is inconsistent using Gaussian elimination.

    4. What does it mean for two matrices to be equal?
